摘要：

The estimation of steady state and dynamic parameters is indispensable to extract maximum power from solar photovoltaic system. This article aims to extract steady state and dynamic parameters for a low-concentration photovoltaic system under actual test conditions. A theoretical model is reported to estimate dynamic resistance under varying concentration and temperature for low-concentration photovoltaic system. When the concentration ratio is changed from 1 sun to 5.17 suns the maximum power delivered by low-concentration photovoltaic system increased by threefold. The results show that the higher solar PV module temperature has negative impact on the open circuit voltage for a given concentration with negative temperature coefficient of approximate to -0.021 V/K. The observed dynamic resistance was in the range of 17.99 to 24.84 Omega for the low-concentration photovoltaic system under actual test conditions. (C) 2013 Elsevier B.V. All rights reserved.
